摘　　要：以宁夏羊角椒雄性不育两用系为试材,对其可育系与不育系的叶片和不同发育时期花蕾的可溶性糖、可溶性蛋白质和游离脯氨酸含量进行测定并比较分析,以了解宁夏羊角椒雄性不育两用系物质代谢的差别。结果表明:可育系的不同时期花蕾中与叶片的可溶性糖含量均明显高于不育系,小花蕾时期的可溶性糖含量最高,可溶性蛋白质含量差别不明显;随着花蕾的发育,不育系和可育系中的脯氨酸含量均逐渐增加,不育系花蕾和叶片中的脯氨酸含量明显低于可育系。说明宁夏羊角椒雄性不育系的营养代谢的缺陷是表现在整个植株的,而不是只表现在花粉的发育过程中。A new pepper（Ningxia Cavel）male sterility line and its fertility line were used as materials,which were discovered by Ningxia Academy of Agriculture and Forestry Sciences.The content of soluble sugar,soluble protein and free proline in efferent bud′s stage and the leaves of male sterility line and its fertility line were measured and analyzed.The results showed that the content of soluble sugar,soluble protein and free proline in different bud′s stage and the leaves of male sterility resource was higher than its fertility line.The content of soluble sugar in the small bud was the highest in the three stages of flower development.The difference about content of soluble protein was not obvious.The content of free proline reflected an increasing tendency during flower development.That Ningxia horn pepper male sterile lines of nutrition metabolic defects were shown in the whole plant,not only in the process of pollen development.
